This book for the first time thoroughly investigates the extent of economic and institutional integrations and the underlying governance reshuffling process of China’s city-regionalism. By using the Shenzhen-Dongguan-Huizhou sub-region (SDH) in southern China as an empirical case, this book provides convincing evidence that China’s city-regionalism is essentially a state-orchestrated and institution-based process. Perspectives from “market-industry-infrastructure” and multi-level governance (MLG) have been provided to systematically examine China’s city-regionalism. This book has essentially made a definitive contribution to China’s regional governance. Methodologically, it shows how China’s city-regionalism can be examined through a problem-solving and case-by-case paradigm, through building a bridge between an empirical slogan and an inclusive theoretical term for institutional integration and through MLG and its integrative approaches in China. Exhilarating findings are presented using extensive tables, graphs, and maps along with the integration of quantitative and qualitative methods. Undergraduates, graduates, and researchers who are interested in China’s city-regionalism and regional governance would be the readership of the book, and officers from different levels of government as well as policymakers will find the book inspiring.
